Sjoerd Meijer 857469dbb1 [ARM] Do not fuse VADD and VMUL on the Cortex-M4 and Cortex-M33 
A sequence of VMUL and VADD instructions always give the same or better
performance than a fused VMLA instruction on the Cortex-M4 and Cortex-M33.
Executing the VMUL and VADD back-to-back requires the same cycles, but
having separate instructions allows scheduling to avoid the hazard between
these 2 instructions.
